Why are we trying to dynamically get the list of .pyc files in Makefile.in?
Why not just pre-compute the .pyc list and pass it to rm -f during
make fast-clean? Let's just put the list into build-outputs.mk.
The TEST_PROGRAMS variable probably already contains the list of .py
files corresponding to the .pyc files we want to remove.
It could be very simple to make gen-make.py add the corresponding
.pyc files to the CLEAN_FILES variable.

Speaking of which, rm -f $(CLEAN_FILES) could also end up being too
long on certain types of UNIX. So maybe put .pycs into a different list.
Or if we can find out the minimum length supported by systems still in
use today, we split up CLEAN_FILES accordingly, and run
rm -f $(CLEAN_FILES1); rm -rf $(CLEAN_FILES2); ... etc.
